\subsection{Entertaiment Games}
There are some RTS games features, like competitive environment, the existence 
of the currency or the rationally behavior supposed for opponents and other 
units of the game that make this games perfect test platforms for multi-agent 
systems.

In addition, this type of platforms allows to model almost any kind of 
environment and enables explicit communication and collaboration in order to be
able to solve certain tasks.  In fact, RTS games are  a good simulation of real
use environments of multi-agent systems.

Also the use of multiagent systems is very suitable for many different kid of games,
not only RTS games, also first person shooting games, having a good AI that controls the enemies
making them play coordinated. Also the same idea can be applied to Massively multiplayer online role-playing games, thatmany times when the other player are not persons is to easy to detect it, and even more have a multiagent system controlling 
your player when you have to sleep having decided previously which are the believes and desires that we want to achieve.

In the field of games there are many possible options.

\subsection{Serious games}
\label{sec:SeriousGames}
It is called \emph{Serious
games}\footnote{\url{http://en.wikipedia.org/wiki/Serious\_game}} to a game that has a primary purpose other
than entertainment. They are used as a mean to train, educate or simulate in
fields like medicine, the military, emergency management, health care, etc.

These games try to simulate a specific field of knowledge in order to obtain a
simulated environment where practice by the students is not as costly or
dangerous as the real environment could be. For instance, fresh firemen can
simulate a fire in a crowded place, and learn how to react to different
situations without being involved in the real fire.

Agents can play an important role here, by means of taking control of the NPCs
(Non Playing Characters) in the game or by controlling the opposing force. That
opposing force could be a real enemy in the military simulation or it can be the
nature trying to ``defeat'' the firemen creating difficult fires to extinguish
or emergency situations in the hospital management games.

\subsection{Group Robotics}
The features that make RTS games challenging for AI are the same features that
make that results obtained on this environments are applicable to real world.
Therefore, is not strange that solutions found for virtual agents, with
problems like dynamic environment, or partially unknown environment; are 
transferred to situated agents, with problems like dynamic environment, or 
partially unknown environment.

In the same way, in these games it is possible to find implementations of 
techniques originating from the area of robotics. Sometimes as a one more way 
to export knowledge, for the same reason said before, and sometimes for 
testing. Examples of this are navigation techniques, developed for mobile
robots, but currently widely applied in RTS games.
